Subject: [PATCH RFC 0/3] rust: tty: introduce TTY subsystem abstractions
 and rttyprintk

Hello,

This RFC patch series introduces Rust abstractions for the
TTY subsystem and implements a sample driver, rttyprintk.

Currently, TTY abstractions are missing in the
Rust for Linux implementation. This series aims to fill that gap.

It consists of two main parts:
- Rust TTY abstractions
- The rttyprintk driver
rttyprintk serves as the first example of a Rust TTY driver.
I chose to port ttyprintk because its simplicity makes it and 
ideal candidate for validating the new abstractions and demonstrating
their usage.

Thank you!
